Khan Kurebir of Mongolia (789-840) was the Khan of the Uyghur Khaganate from 839 to 840, succeeding Khan Hu of Mongolia and preceding Khan Oge of Mongolia. He seized power with the Hosa clan in 839, but he was later beheaded and the Ediz clan restored.

Biography
Kurebir was a minister of the Uyghur Khaganate from the Manichaean Hosa Uyghurs, one of the clans loyal to the Ediz clan that ruled the khaganate. Kurebir had his own ambitions, and in 839 he invited 20,000 Shatuo horsemen from Ordos (present-day Inner Mongolia, China) to help him seize the throne, and he forced Khan Hu of Mongolia to commit suicide. In that one year, there was an epidemic and a severe winter that killed most of the Uyghur livestock, causing a famine. In 840, Uyghur minister Kulug Bagha fled to the Yenisei Kirghiz and invited them to invade from the north, and 80,000 Kirghiz sacked the capital of Ordu Baliq in present-day central Mongolia, razing it to the ground. Kurebir was captured and beheaded, and the Kirghiz went on to destroy other cities throughout the empire, burning them to the ground. Kurebir was succeeded by Khan Oge of Mongolia, who restored the Ediz.
